Introduction: The utilization of advanced practice providers (APPs) in oncology has been growing over the last decade; however, there is no standard method for assessing an APP's contributions to oncology care., Methods: The NCCN Best Practices Committee (BPC) created an APP Workgroup to develop recommendations to support the roles of APPs at NCCN Member Institutions. The Workgroup conducted surveys to understand how NCCN centers measure productivity. This article will review the survey results and provide recommendations for measuring APP productivity., Results: Although 54% of responding centers indicated they utilize relative value units (RVU) targets for independent APP visits, 88% of APPs are either unsure or do not believe RVUs are an effective measurement of overall productivity. Relative value units do not reflect non-billable hours, and APPs perform a significant number of non-billable tasks that are important to oncology practices. Sixty-six percent of APPs believe that measuring disease-based team productivity is a more reasonable assessment of APP productivity than measuring productivity at the individual level., Conclusion: Our recommendation for cancer centers is to focus on the value that APPs provide to overall care delivery. Advanced practice provider productivity metrics should consider not only the number of patients seen by APPs, but also the high quality and thorough care delivered that contributes to the overall care of the patient and practice. Advanced practice providers can help improve access to care, deliver improved outcomes, and increase patient and provider satisfaction. Reducing the focus on RVUs, accounting for important non-RVU-generating activities, and incorporating quality and team metrics will provide a better overall picture of APP productivity., Competing Interests: The authors have no conflicts of interest to disclose., (© 2022 Harborside™.)

Introduction: The National Comprehensive Cancer Network (NCCN) Best Practices Committee created an Advanced Practice Provider (APP) Workgroup to develop recommendations to support APP roles at NCCN Member Institutions., Methods: The Workgroup conducted three surveys to understand APP program structure, staffing models, and professional development opportunities at NCCN Member Institutions., Results: The total number of new and follow-up visits a 1.0 APP full-time equivalent conducts per week in shared and independent visits ranged from 11 to 97, with an average of 40 visits per week (n = 39). The type of visits APPs conduct include follow-up shared (47.2%), follow-up independent (46%), new shared (6.5%), and new independent visits (0.5%). Seventy-two percent of respondents utilize a mixed model visit type, with 15% utilizing only independent visits and 13% utilizing only shared visits (n = 39). Of the 95% of centers with APP leads, 100% indicated that leads carry administrative and clinical responsibilities (n = 20); however, results varied with respect to how this time is allocated. Professional development opportunities offered included posters, papers, and presentations (84%), leadership development (57%), research opportunities (52%), writing book chapters (19%), and other professional development activities (12%; n = 422). Twenty percent of APPs indicated that protected time to engage in development opportunities should be offered., Conclusion: As evidenced by the variability of the survey results, the field would benefit from developing standards for APPs. There is a lack of information regarding leadership structures to help support APPs, and additional research is needed. Additionally, centers should continuously assess the career-long opportunities needed to maximize the value of oncology APPs., Competing Interests: The authors have no conflicts of interest to disclose., (© 2021 Harborside™.)

Background: Increased expression of Ca2+-sensitive protein kinase C (PKC) isoforms may be important markers of heart failure. Our aim was to determine the relative expression of PKC-beta1, -beta2, and -alpha in failed and nonfailed myocardium., Methods and Results: Explanted hearts of patients in whom dilated cardiomyopathy or ischemic cardiomyopathy was diagnosed were examined for PKC isoform content by Western blot, immunohistochemistry, enzymatic activity, and in situ hybridization and compared with nonfailed left ventricle. Quantitative immunoblotting revealed significant increases of >40% in PKC-beta1 (P<0.05) and -beta2 (P<0.04) membrane expression in failed hearts compared with nonfailed; PKC-alpha expression was significantly elevated by 70% in membrane fractions (P<0.03). PKC-epsilon expression was not significantly changed. In failed left ventricle, PKC-beta1 and -beta2 immunostaining was intense throughout myocytes, compared with slight, scattered staining in nonfailed myocytes. PKC-alpha immunostaining was also more evident in cardiomyocytes from failed hearts with staining primarily localized to intercalated disks. In situ hybridization revealed increased PKC-beta1 and -beta2 mRNA expression in cardiomyocytes of failed heart tissue. PKC activity was significantly increased in membrane fractions from failed hearts compared with nonfailed (1021+/-189 versus 261+/-89 pmol. mg-1. min-1, P<0.01). LY333531, a selective PKC-beta inhibitor, significantly decreased PKC activity in membrane fractions from failed hearts by 209 pmol. min-1. mg-1 (versus 42.5 pmol. min-1. mg-1 in nonfailed, P<0.04), indicating a greater contribution of PKC-beta to total PKC activity in failed hearts., Conclusions: In failed human heart, PKC-beta1 and -beta2 expression and contribution to total PKC activity are significantly increased. This may signal a role for Ca2+-sensitive PKC isoforms in cardiac mechanisms involved in heart failure.
